Weber 2 X 34 Ict Conversion Kit

anyone have experience or remarks on this dual weber kit for a stock 74 1.8
Currently it has a single progressive carb, the dual 40idf is nice but costly and wouldnt the dual 40idf kit be excessive for a basically stock 1.8

Probably not the best performance carb set but I've seen guys brag about 35 mpg with them.

not too concerned about the mpg because I will only burn about 2-3 tanks a year but how much fuel do I need to stuff into a stock engine? I would like to a\x the car a few times and would like at least some decent acceleration. What would dual idf40's give me on a stock engine that these wont, top end?

Don't waste your money....keep the single carb until you save up enough for the dual Weber 40 IDF set up using the CB Performance linkage...much better performance....even better with a cam change

I dont plan on opening the motor for a long time as the moror was rebuilt by the PO, good compression, no smoke, no leaks, if I dont have to. Would I be getting better low end performance with the 40's if so I will take your advice. Do you know this from experience? and thanks for the responses! I do plan on going with an msd 6a and optical dizzy.

earlr85944....yes I have first hand experience with weber 40/44 idfs on the type 4 17./1.8/2.0
done it many times....I know for a fact that you would end up not being happy with the icts and would just end up getting the 40 idfs anyway...I promise!!!
With the msd 6a and dual 40idf webers you will feel the difference....good response from low end to top end....(much better with a carb cam)....but will work just fine with the stock cam...I understand not wanting to just split the case yet....
be prepared to do a little re jetting and tuning....get a Synchrometer....and the CB linkage...hands down the best...just plain works
This way you will have one choke/barrel per cylinder....the 40 idfs are very tunable...
The dual 40 IDF set up will work well for you doing the autox and who cares about fuel economy from a fun car...right...really it just fine...I didn't ask what dizzy you have with the single carb set up...you may already have this change....but you should change the dizzy also.....the Bosch 009/050 work well or the Mallory/MSD ones...
Good Luck on the project....you will have fun and have a better running engine...John

Thank you John, I will wait on the 40's. I've got the synchrometer from the 912 tuning days. Btw how can I id the current distributor?

You won't have any problems since you tuned the Solex carbs on a 912....you're ready to go..
The dizzy has numbers on the side....there is both a Bosch and VW number...yank it out or get a good light and mirror and see if you can read them......does it have a vacuum advance on it?? We're using a Mallory distributor right now in a track 914 and it works very well...

I've been involved in a few conversions with duel singles and love them.
I think that your car is perfect for the conv. I ran one as a driver for a year and a half. Just put those carbs on my new driver. A 73 Bug. I can't tell you how much MPG cause the O.D. didn't work. But it didn't have a lack of power.
The stock cam and dist work fine with carbs on the L-Jet but D-Jet is another story. It lacks top end. But gets great MPG. Linda Horne's car got 49.16 MPG. That was an accident. We just put the carbs on the car and she drove to AZ for the Route 66 Classic and on the way back used 6 gallons of fuel to go 295 miles. Linda's car has 205 50 15's on and a 009 dist. So we were not looking for MPG.
Putting those carbs on your car will let you enjoy the car. You will probably be happy enough to leave them.
Linda's carbs.

Linda's car and my car.

Are Djet Cams and Ljet Cams different? or just the distributors?

50 mpg would make me think of scrapping the D jet. Best I've ever gotten is about 32

In theory, the cams for all of the non-hydraulic Type IV motors were the same. In practice, there were some smallish changes. I think that by the time they were building 914 motors, though, they really were down to one specific cam.

The carbs on Linda's car are Solex 40's. I think the 34's are more suited to the 1.7 and 1.8. We put the Solex's on her car cause it's what we could get at the time.

My take? It's not fuel injection, so it's "black magic" and I don't unnerstand it!!

Soo... I guess I'm old school. But I never could understand why they went to injection when you can do so much with carbs.
I had to buy a LM-1 (O2 sensor) to tune my D-Jet.
It's my understanding that the factory did put carb's on some cars.

Joe, I love ya man!
Yup, the factory did put carbs on, back in the day.
I would never argue with you. You could make carbs out-tune the latest FI on a stock cam, and then walk the crew over to a BBQ that would make them renounce FI forever.
Dang, I gotta come to one of those.

This thread has intrigued me. I MUST HAVE A PROBLEM

I have a '75 914 1.8 with dual IDF 40 carbs, MSD 6A, 009 Dizzy

And I am only getting 15-18 mpg, could I have it mis-tuned? It runs pretty good, not as fast as my 944 but I don't expected to be.

Trying to think of a good reason for the difference. What I was thinking was that you have 4 jets feeding the engine and that the engine likes to be rich and the difference is 4 jets being rich instead of 2. Except that we're still just mixing volumes at a ratio around 14:1.

I time Linda's car at 27* at full advance. She has a 009.
Thomas car had 34 PICT's. Thomas used a 050 timed a 30* and Thomas was happy A/X'ing the car. He also got repeated MPG over 35.
We tried an 010 and an 018 but they didn't work very well either.
Both these car were worn D-Jet motors with stock cams.
Hope this helps.

Spievy...I don't think you have a problem...I would say that is about right for the 1.8 with the 40 weber carbs and is pretty good...also the 944 should be faster....just handles differently
